Revert "[dawn][vk] Fix uses of pipeline robustness when robustness is disabled."

This reverts commit 20039ea00f3139d13c5ebe85a11c58f2df21c06b.

Reason for revert: breaks the roll into g3, revert before investigating.

Original change's description:
> [dawn][vk] Fix uses of pipeline robustness when robustness is disabled.
>
> When Dawn's robustness is disabled we use pipeline robustness to tell
> the driver to not do any robustness if it can, so we still need to
> enable the Vulkan extension in that case, to allow passing
> VK_PIPELINE_ROBUSTNESS_BUFFER_BEHAVIOR_DISABLED_EXT.
>
> When robustness is disabled we also need to skip setting the
> VulkanUse*RobustAccess2 toggles since the relevant features are not
> enabled, which would cause a VVL error when they make pipeline
> robustness request "robust access 2".
>
> Fixed: 443940959

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the WebGPU standard. More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL. Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.

Dawn provides several WebGPU building blocks:

  • WebGPU C/C++ headers that applications and other building blocks use.
    • The webgpu.h version that Dawn implements.
    • A C++ wrapper for the webgpu.h.
  • A “native” implementation of WebGPU using platforms' GPU APIs: D3D12, Metal, Vulkan and OpenGL. See per API support for more details.
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
  • Tint is a compiler for the WebGPU Shader Language (WGSL) that can be used in standalone to convert shaders from and to WGSL.
